Advances in HCV Therapy
Hepatitis C is a devastating illness which has the potential in the majority of cases to lead to significant morbidity and mortality. Worldwide, the number living with chronic hepatitis C approaches 185 million. Up until recently, the regimen of peg-IFN and ribavirin stood as the standard of care and is still commonly used as first line therapy. This is rapidly changing. Direct acting antivirals have altered the landscape drastically. By understanding the genome of the hepatitis C virus, scientists and researchers have been able to exploit its mechanism of transmission by creating inhibitors against several of the nonstructural proteins that are integral to HCV replication and function [NS3/4 protease, NS5A polymerase, and NS5B polymerases (nucleoside and non-nucleoside)]. The previously reported 50%-70% SVR rates achieved with peg-IFN and RBV are no longer the standard of care. Thanks to direct acting antivirals, IFN free as well as “all oral” regimens are being used to treat HCV. In addition to this, ribavirin-free regimens are also available. These highly effective therapies also provide far less side effects and accomplish better results in less time, thus shortening treatment duration significantly. Additionally, even in the notoriously difficult -to-treat populations, results have been promising.
